Title: Communication system using elastic wave
Inventor: FURUKAWA HIROSHI
IPC: H04W84/10
Filed: 2001-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a communication system, where new electromagnetic waves do not have to be allocated and which suppresses an influence given to a human body and also uses an elastic wave capable of utilizing all kinds of daily objects existing in the environment as a transmitting medium. SOLUTION: Each of communication nodes 100-1 to 8 is arranged fixedly or is movably. The communication nodes 100 include not only a personal computer, a portable telephone set and an information terminal of a portable information terminal but also peripheral devices, such as a keyboard, a printer and a display. The elastic wave is used to transmit and receive information in the communication nodes 100-1 to 8, and then communication lines 101-1 to 15 use an elastic body as a transmission medium. When air is selected as the elastic body of the transmission medium, transmission and reception in which an acoustic wave (ultrasonic wave) is used as a transmission means is realized. When the elastic body of the transmission medium is a solid body, objects existing in the environment such as a desk, a wall and a table become a transmission medium.  There may be cases in which the elastic body of the transmission medium is a liquid.

IPC: H04B10/2519
Filed: 2001-02-07
Abstract: PROBLEM TO BE SOLVED: To provide such a small distribution equalizer using a chirp fiber grating at a low cost as group delay ripples can substantially be disregarded. SOLUTION: A fiber grating 2 and a metal rod 3 which are manufactured from a electron beam phase mask without connection error, are unified through a polyethylene sleeve to form a beam 5. When assuming that z0 and l are constants and r is the radius of a fiber, a linear deformation distribution is applied by inserting the beam 5 into a groove 7 of a curved line z(x) expressed by (6z0/l3)(lx2/2-x3/3)-r<z(x)<(6z0/l3)(lx2/2-x3/3)+r formed on the substrate 6 including x-z rectangular coordinates. The fiber grating in the beam 5 is thus converted to a chirp fiber grating, and used as a wavelength dispersing medium.
